A LAS file is a binary format designed to store 3D point cloud data, primarily originating from LiDAR or similar scanning technologies. Each point in the file typically contains:

X: Horizontal coordinate (e.g., easting or longitude)

Y: Vertical coordinate (e.g., northing or latitude)

Z: Elevation or depth (typically in meters)

Additional attributes: (depending on LAS version and software)

- Intensity
- Return number
- Classification (e.g., ground, vegetation, buildings)
- GPS time
- RGB or NIR values

Example (interpreted values from LAS – binary not human-readable):

To be compatible with our preview and processing tools, your LAS file must meet the following requirements:

Must be a valid LAS or LAZ binary file

File extension must be <code>.las</code> or <code>.laz</code>

File must conform to LAS 1.2, 1.3, or 1.4 specifications

Point data format should be 0–3 (basic) or 7–10 (extended attributes)

Coordinate system must be embedded in the file via the <code>GeoTIFF</code> keys in the LAS header

WKT or EPSG code preferred if CRS is supplied externally

- Must be a valid LAS or LAZ binary file
- File extension must be <code>.las</code> or <code>.laz</code>
- File must conform to LAS 1.2, 1.3, or 1.4 specifications
- Point data format should be 0–3 (basic) or 7–10 (extended attributes)
- Coordinate system must be embedded in the file via the <code>GeoTIFF</code> keys in the LAS header
- Z-units must be in meters
- WKT or EPSG code preferred if CRS is supplied externally

LAS files can include CRS data, but:

If the CRS is embedded (via LAS header VLRs and GeoTIFF keys), it will be automatically detected

If no CRS is detected, you may manually specify it, but this will not modify the original file

- If the CRS is embedded (via LAS header VLRs and GeoTIFF keys), it will be automatically detected
- If no CRS is detected, you may manually specify it, but this will not modify the original file

This format is supported when exported from the following software packages:

- Qimera
- Fledermaus
- CARIS

- LASTools
- CloudCompare
- PDAL

- Leica Cyclone
- Trimble Business Center

File extension is <code>.las</code> or <code>.laz</code>

Points contain X, Y, Z and optionally intensity, classification, color, etc.

- File extension is <code>.las</code> or <code>.laz</code>
- File conforms to LAS 1.2–1.4 format
- Points contain X, Y, Z and optionally intensity, classification, color, etc.

Ensure point format is supported (0–3 or 7–10)

Confirm coordinate system information is embedded or provided

- A sample <code>.las</code> or <code>.laz</code> file
- Information on source software used

1. Check that the LAS file is not corrupted
2. Ensure point format is supported (0–3 or 7–10)
3. Confirm coordinate system information is embedded or provided
4. Contact our support team with:
 - A sample <code>.las</code> or <code>.laz</code> file
 - Information on source software used
